Kim Hyok-chol

Kim Hyok-chol (died March 2019) was the North Korean career diplomat who served as the nuclear envoy to the United States under Supreme Leader Kim Jong-un. He took part in a summit with US president Donald Trump at Hanoi, Vietnam in February 2019, handling working-level negotiations. However, the summit failed when Trump imploded, provoking Kim Jong-un's wrath. Kim Hyok-chol was executed for his failure, while three other officials were sent to perform hard labor as punishment.
